The radius, distance, length of the sidereal day, and average blackbody temperature of the planets are shown, and the distance, luminosity relative to the sun, spectral class, surface temperature, and radius of stars are indicated. Information about the objects that Celestia draws can also be displayed. The names and positions of multitudes of objects in space can be displayed, from galaxies, star clusters, nebula, constellations, and stars to planets, moons, asteroids, comets, and artificial satellites, as well as the names and locations of cities, craters, observatories, valleys, landing sites, continents, mountains, seas, and other surface features.Ĭelestia displays such features as detailed atmospheres on planets and moons, planet shine on orbiting satellites, sunsets and sunrises, moving clouds, planetary rings, eclipse and ring shadows, constellation lines, borders and illustrations, night-side lights (of cities), detailed surface textures, specular reflections off water and ice, nebula gases, and star flares. The time simulated by Celestia can be set at any point in the future or past, although planetary orbits are only accurate within a few thousand years of the present day, and date arithmetic overflows at the year 5874774. Controls allow users to orbit stars, planets, moons, and other space objects, track space objects such as spacecraft, asteroids, and comets as they fly by, or travel to and/or fly through nebulae and irregular, elliptical, and spiral galaxies (over 10,000 galaxies included). Viewpoints can be set to look forward, backward, or at any angle to direction of travel.

Using simple keyboard controls, Celestia users can travel/fly through the Celestia universe at any speed from 0.001 m/s to millions of light years per second. The user can vary the number of stars that are visible on the screen and have them drawn in different styles. This makes it possible to provide a solar and lunar eclipse finder and to display the orbital paths of planets (including extrasolar planets), dwarf planets, moons, asteroids, comets, artificial satellites, and spacecraft.

Celestia uses the very accurate VSOP87 theory of planetary orbits. Ī simulated supernova of the star Betelgeuse as seen from Earth in Celestia.Ĭelestia displays the Hipparcos Catalogue (HIP) of 118,322 stars.

Since then, some of its development team have gone to work on either Celestia.sci, a cosmological visualizer or SpaceEngine, a similar software but featuring more realistic graphics.

There are three graphical front-ends available: GLUT, GTK+ or Qt.Ĭelestia's final update came in 2011. Celestia is free software released under the GNU General Public License.

Ĭelestia is available for AmigaOS 4, Linux, Mac OS X, and Microsoft Windows. NASA and ESA have used Celestia in their educational and outreach programs, as well as for interfacing to trajectory analysis software. Celestia displays and interacts with objects ranging in scale from small spacecraft to entire galaxies in three dimensions using OpenGL, from perspectives which would not be possible from a classic planetarium or other ground-based display. The program is based on the Hipparcos Catalogue (HIP) and allows users to travel through an extensive universe, modeled after reality, at any speed, in any direction, and at any time in history.
